I getting php version error message in my site.
I have two magento instance in same server, One is ruining & another is not running. Please share idea/answer with me.
As far as I can see it could be one of the following things:
1) Corrupt index.php in your magento root dir.
2) Incorrect virtual host set up resulting in php not executing the code in index.php
Could you post your apache site configuation and or your index.php
If you look in the source of the page you will see the entire index.php file listed. it happens the same if you call
cron.php. This makes me thing that you don't have php installed on the subdomain
